RESILIENT WHEEL.

Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed August 19, 1914. Serial No. 857,439.

To all whom it may concern: 7 g v Be it known that 1, JOHN B. DRAI-oNov- SKY, a citizen of the United States, and F681- dent of Milwaukee,in the county of .Mil

waukee and State of lVisconsin, have invented new and usefulImprovementsin Resilient VVhee'ls, of which the. following is adescription, reference being had to the accompanying drawings, which area part of this specification.

The invention relatesto resilient wheels.

The invention designs to provide a resilient wheel of the spring type,having movable wheel members resiliently supported.

The invention further designs to provide a resilient wheel in which thehub portion of the wheel is yieldingly mounted within the wheel proper,to cushion the wheel against shocks and vibration due to theinequalities of the road traveled over.

The invention further designs to provide a resilient wheel having meansfor adjusting the tension of the resilient members.

The invention further designs to provide a resilient wheel whereby thestrain of the load is equally distributed to all of the resilientmembers of the wheel.

The invention further designs to provide a resilient wheel comprisinginner and outer hub members, and cushioning means be tween said hubs,comprising springs which are actuated by the movement ofthe hub members,and which are yieldingly supported upon sliding rings mounted upon theinner hub member, thus eliminatingconnecting bolts between the rings,which it has been found in practice are objectionable because oftheirtendency to twist and break off. J

The invention further designs to provide a new and improved form-ofresilient wheel.

The inventionconsists in the several features hereinafter set forth, andmore particularly defined by claims at the conclusion hereof. I

In the drawings: Figure 1 is an elevation of the device embodying theinvention (parts being broken away and shown in section); Fig. 2 is asection taken on the line 2-2 of Fig. 1; Fig. 3 isia section taken onthe line 33 of Fig. 1; Fig. 4- isja view similar to Fig. 1, of aslightly modified form of the device; Fig. 5 is a section taken. on

the line 55 of Fig. l; Fig. 6 is a detail the ring lat and the flange,of the ring 13,.

forming a space therebetween, for receiving the spokes. of the wheel,which may be secured by bolts 15 passing through them and the apertures16 in the members 13 and 14.

The flanged ring 13 is provided with a depending flange 17 having aseries of apertures 18 and 19 therein, whose purpose is hereinafterdescribed.

The inner hub 12 comprises a hub member 20, which is designed to fituponthe axle 21, and has a flange 22 at one end with which the casing 23slidably engages, said (casing being connected to the flanged ring 13.The

front of the hub and the mechanism therein isinclosed by the casing 24,which fits over it, and is secured to the ring 14 of the outer hub. Theinner hub is provided withan upwardly projecting ring portion or flange.25, and a ring 26 similar to the flange 25, is detachably secured to thehub 12, the ring 26v and flange 25 forming a space or guide forthe loweredge of the downwardly pro-.

jecting flange 17.

The means for cushioning the two hub members, comprises aplurahty ofhorizon.-

tally disposed springs 27 extending through the apertures 18, and whichare adjustably secured at their ends by means of bolts 28 havingcone-shaped heads 29 to conform to the cone-shaped ends of thesprings,to a

pair of rings 30 which are slidablymounted upon the'hub 12, and meansare provided for transmitting the force exerted upon the outer hub tothe springs, comprising bearing cup holding members 31 and 32 havingre-1 cesses 33 and 34 positioned opposite to one another, to hold thebearings 85 therebe: tween. The bearing cup holdingpmembers 31 aresecured to the flange 17, by pins pass-- ing throughthe apertures 19,while the bear ing cup holding members 32 are secured to the rings 30,said cup holding members being shouldered as at 36 in Fig. 2, andfriction rings 37 being interposed between them and the rings and flange17. As previously pointed out, the rings 30 are slidably mounted uponthe hub 12, and to prevent rotation relative thereto they are recessedas at 33 to receive keys 39 which are also mounted in key slots 40 inthe hub 12.

The tension of the springs 27 may be adjusted by varying the length ofthe bolts 28 by'ineans'of the nuts 11, and in place of the ball bearingsshown in Figs. 1 and 2, roller-bearings 42 shown in Figs. 1,, 5 and 6,and ball bearings 43may be used between the hearing holding cups and therings and flange, in placeof the friction rings 37, and rubber 44 may beinserted within the outer hub 10; to keep the cup holding members 32 inalinement.

The operation of the device is as follows: Any vertical movement of theouter or inner hubs with respect to each other, will cause a likemovement of the flange 17 and rings 30, which are connected to themrespectively, which will move the bearings 34 or 42, causing them toascend or descend in their seats in the cup holding members.

This will result in the exertion of a force tending to move the rings 30outwardly and away from each other, which will be compensated for byan'opposite force exerted by thesp'rin'gs 27-. Thus for every forceexerted upon the hub members, there will be a corresponding forceexerted against the rings 30, which will be counteracted by the springs27, andthe springs being mounted ,u'pen the rings the force will beuniformly distributed among them. It will be noted that the rings 30'are free to move outwardly upon the keys 39 on the hub, and that by thesame construction the rings 30 are preso that there will be no twistingaction exerted upon the springs 27, but simply a straight pull, and theuse of conneeting bolts between the rings 30 is eliminated. Theinvention thus exemplifies a resilient wheel comprising inner and outerhubs and cushioning means between the hubs,

comprising a plurality of horizontally dispose'd' springs which aresupported at their en'dsfion a pair of rings which are forced away from,or moved toward, each other, by the movement of the hub member's.

What I claim is":

1. A resilientwheel comprising inner and outer hub members, a pair ofrings slidably mounted upon said inner hub members,

means for preventing rotation of the rings upon said mernbers comprisinga key, a plurality of tension springs interposed between said rings andfixedly secured thereto at bearing cups carried by said dependingflange, a ring on either side of said bearing cup holding flange,bearing cup holding members carried bysaid rings, bearings disposed inthe cups formed by said cup holding members, and resilient means fixedlysecured to the rings, whereby movement of the movable members will causethe ringsto move outwardly against the action of said springs. i

3. A resilient wheel comprising movable inner and outer hub members, oneof said members having a' depending flange, the other of said membershaving a pair of flanges forming a guidew'ay therebetween for thedepending flange of the other member, rings slidably mounted upon one ofsaid members, a plurality of springs interposed between said rings andfixedly secured thereto at their ends, and means on the other of saidmovable members and said rings for permitting the rings to moveoutwardly against the action of said springs.

4. A resilient wheel comprising movable inner and outer wheel members, asliding connection between said members, rings slidably butnon-rotatably mounted upon one of said members, a plurality of tensionsprings interposed between said rings and fixedly secured thereto attheir ends, and means on the other of said movable members and saidrings for permitting the rings to move outwardly against the action ofthe springs.

5. A resilient wheel comprising movable wheel members, one of saidmembers having a flange provided with a plurality of apertures, ringsslidably but nonrotatably mountedup'on the other of said members, aplurality of horizontally disposed tension springs interposed betweensaid rings and fixedly connected thereto at their ends andpassingthrough the apertures in said flange, and means on said flangeand said rings for permitting the rings to move outwardly against theaction of said springs.

In testimony whereof, I aihx my signature in presence of two witnesses.
